Title: Safety device for filtering dust separation elements
Inventor: WEBER EKKEHARD PROF DR ING
IPC: B01D46/42
Filed: 1988-03-26
Abstract: To prevent dust breakthroughs when individual filter elements are damaged, a safety device is proposed which comprises a finely perforated metal sheet which is mounted at the filter element exit towards the clean gas side. The perforated metal sheets have hole diameters between 5 and 250  mu m and have a resistance to flow of at most 200 Pa during fault-free operation. In the event of the filter element being damaged, the dust passing through is deposited on the perforated metal sheet, as a result of which the resistance to flow of the perforated metal sheet increases and the defective filter element is automatically taken out of operation.

Title: Distance measuring arrangement
IPC: G01B11/30
Filed: 1988-07-18
Abstract: An arrangement to measure the distance of a test point lying on a specimen surface from a reference plane comprises a semiconductor laser (10), whose power is readjusted so that a constant quantity of light falls on a detector (22), independent of the reflection capability of the specimen surface at the test point, the said detector generating an output signal corresponding to the focal point deviation of the test point. The output signal of a position transmitter (50) which measures the actual position of an optical unit (16), which serves to image the laser beam on the test point and is tracked so that the test point always lies at the focal point, is combined by means of an addition circuit (66) with a correction signal which is derived from a signal assigned to the actual power of the semiconductor laser (10). <IMAGE>

Title: Antilock hydraulic brake system
Inventor: LUETTEKE HARALD DR
IPC: B60T8/44
Filed: 1988-12-19
Abstract: The pressure in the wheel brakes can be controlled by means of an inlet valve 15 and an outlet valve 17 as a function of its rotational behaviour. Pressure medium from the pumps 13 is fed to the wheel brake by way of the inlet valve 15 and pressure medium removed by way of the outlet valve 17. The valves 15, 17 are solenoid-actuated seat valves, which generate considerable control noise. By inserting a differential pressure limiter upstream of the inlet valve 15, at least the noise developed by this valve can be considerably reduced. It has furthermore been shown that the control performance can be improved. <IMAGE>
Patent DE-3900322-A1 (DE)
Title: Water heating boiler
Inventor: ZEIMES MANFRED
IPC: F24H1/32
Filed: 1989-01-07
Abstract: In water heating boilers which have a combustion chamber and a downstream heating surface and consist of hollow members (3) through which heating water flows and which have sealing strips (7), the difficulty arises, particularly at the colder downstream heating surfaces, that the dew point of the heating gases is frequently undershot. In this case corrosively active liquids are deposited from the heating gas. Given effective thermal use of the exhaust gases, the undershooting of the dew point temperature at the heating surfaces can be avoided by providing that the width (13) of the member (3) together with the sealing strips (7) is at least twice and at most eight times as large as the inside diameter (14) of the member (3) in the direction of the sealing strips (7), and that the wall thickness (9) of the member (3) decreases towards the middle (10) of the member (3) in the region which is touched by the heating water. This configuration, which conveys the heat flow to the middle (3) of the member has the effect that the surface temperature is high enough to prevent condensation even at the critical points. An effective heat use is achieved owing to the large exchange surface. <IMAGE>

Patent DE-3909194-A1 (DE)
Title: Multiple group plug for electrical connections
Inventor: RITTER HEINZ
IPC: H01R13/645
Filed: 1989-03-21
Abstract: Multiple group plugs must be capable of being associated unambiguously with their mating elements. A known electrical plug connection, consisting of a braid plug and a connecting plug housing, uses interacting coding grooves and latching tabs. In this case, it is disadvantageous that each plug connection, which is designed to have a greater or lesser number of poles, requires its special components. This results in a large number of differently designed plugs and couplings. The multiple group plug according to the invention reduces the wide range of variants to a minimum. The group plug chambers of plug tabs (2) which are not wired up are closed with the aid of a coding piece (5). Unused points and empty chambers are closed by the coding piece (8). The coding pieces (5, 8) can be designed to have one pole or a plurality of poles. A multiple group plug prefabricated in this way can in consequence be coded unambiguously in a versatile manner for any coupling piece having any desired number of poles. The multiple group plug is used for the connection of individual braids and cable harnesses (cable looms), and connects electrical components to one another in so-called group plug wiring systems. <IMAGE>
Patent DE-3911391-A1 (DE)
Inventor: HOFMANN HANS PETER DIPL ING
IPC: B66B5/00
Filed: 1989-04-07
Abstract: The invention relates to a method of detecting physical parameters, in particular motion parameters, of a goods and/or passenger lift, whose car is suspended on a cable pull driven by a driving pulley. It is the object of the invention to propose a test method for such lifts in which there is a reduction in the amount of work by contrast with previously known test methods, while the test quality is simultaneously increased. According to the invention, this object is achieved when the physical parameters of the lift are determined by connecting at least one displacement sensor to the cable pull and/or the driving pulley in order to generate displacement signals, by connecting the displacement sensors to an evaluation unit which contains a time generator, in order to feed the displacement signals to the evaluation unit, and by connecting the evaluation unit to switching points of the control circuit, at which signals are present which control the sequence of motions of the lift, in order to determine physical parameters from the displacement signals and the control signals. The method can be used advantageously to check the drivability of the driving pulley.

Title: Polycrystalline semiconductor film deposition in insulated substrates - using microwave plasma and biasing substrate via HF voltage allows deposition at lower temp. using inexpensive substrates
Inventor: KAWAKAMI SOICHIRO
IPC: H01L21/205
Filed: 1990-04-30
Abstract: The semiconductor film depsn. on insulating substrates uses a microwave plasma enhanced chemical vapour deposn. (MW-PCVD) apparatus which contains, a plasma-generating chamber (701) with a microwave connection. There is also a film-depsn. chamber (702) which is connected with the plasma-chamber via a grid (711). This chamber contains the insulating substrate (713) which is placed on a conductive sample-holder (708). The plasma is generated by admitting a gaseous source material through a connection (705) to interact with the microwave energy which enters via a dielectric window (703). This plasma is directed into the film depsn. chamber while between the grid and the substrate hodler a high frequency (HF) bias is applied of 100-500V with a frequency of 20-500 MHz. The substrate is held at a temp.  of pref. 200-400 deg.C, and the vacuum pressure inside the depsn. chamber is pref. 13.3-667 mPa.  Also claimed is the chamber as described above to which a provision for generating a magnetic field has been added (709). In this case the pressure in the depsn. chamber is pref. 0.133-667 mPa, with the other conditions is the same ranges as before. USE/ADVANTAGE - The method is capable of depositing a polycrystalline film of a semiconducting Group IV element as well as of semiconducting cpds. of Groups II-VI and III-V of the Periodic System.

Title: Electronic offset correction for focus signals in CD player - using microprocessor to add compensation to error signal and offset value stored in memory during calibration at mfg. stage
Inventor: GLEIM GUENTER
IPC: G11B7/09
Filed: 1990-05-31
Abstract: Servo-controlled focussing in optical disc readers is achieved using a four-quadrant photodetector (PD). Theoretically, when focussing is exact, the error signal (FE) from differential amplifier (V1) should be zero. In practice there is usually an offset voltage which must be compensated. This can be achieved by storing the offset value in memory (S) and using a microprocessor (MP) to subtract this offset at an adder stage (SU). The corrected signal is then fed to the control amplifier (V2) which drives the focussing mechanism (SG). ADVANTAGE - Eliminates time-consuming standard practice of compensation by manual adjustment of potentiometer.
